Is there a way to extend the ground part of an HDR to the gound plane of a Hemisphere/Envosphere prop? Thereby getting continuity and ground shadows. If not, why not? This of course primarily applies to Superfly renders.

If you take an image that is made to fit on the inside of a sphere it will deform and look funky if you place it on the P11 construct/ground plane.

There has to be a set up that will take the HDRI and create a dome AND ground seemlessly. Is it really that difficult? I don't know that mapping needed but surely there could be a work around. It would benefit so many users.

Here is what I did to help with the issue. I took bb's envirosphere added one of the free HDRI_SKIES images ... Added the round ground plane from PP11's primitives ... added a texture and a transparency mask to soften the edges. Not the ideal solution, but better.

I discovered something ... for the construct there IS a mask to blend a sky texture with the ground area. Totally like what I did, but built for the construct. It is in the textures for the sand and sky.

]]>https://forum.smithmicro.com/post/3671https://forum.smithmicro.com/post/3671Fri, 24 Jun 2016 00:22:53 GMTI managed to create a ground plane that takes the same equirectangular images that the EnvSphere does.

I was working on software to make it adapt/change its UV mapping so that you can move the camera around and still get the right perspective. However, the math for that is tricky.

You see, the problem is that each UV point of the world as captured in the image corresponds not to a physical location on the ground, but rather to an angle in altitude and azimuth with respect to the viewer/camera.

As a result, the exact location of each UV coordinate DEPENDS on where you put the camera. In my initial try, the camera has to remain at or close to the center of the circular ground plane, otherwise the perspective is very odd.

Another approach to solving this problem would be to move the ground and dome with the camera, so that the camera is always, by definition, at the center of the setup.

Either way, though, you will not be ok with animating/moving the camera through space. Only rotating the camera in place would seem to look natural.

On page 2 I attached a guide I'd made to show how the construct prop is mapped, and also a material room node set-up that can be used to apply the sky part of an equirectangular image intended for a dome to the construct's dome.
